#1 Find the slope given the points (3,-20) and (5,8) *

Artyom0805 [142]

Hey there :)

To find the slope with two points we will need to use the equation $\frac{y^2-y^1}{x^2-x^1}$

$x^1$ $x^2$ $y^1$ $y^2$

( 3 , -20 ) ( 5 , 8 )

Here is what the equation should look like when replaced with the numbers (it will be a fraction) :

$\frac{8 - (-20)}{5 - 3}$

We know that two negatives cancel out and make a positive, so the numerator would actually be 8 + 20.

Solve the fraction and we get $\frac{28}{2}$

28 divided by 2 is 14. The slope is 14.

A 14 foot ladder is leaning against a building. The ladder makes a 45 degree angle with the building. How far up the building do

3241004551 [841]

Sin 45 = X / 14
X = 14 * sin45
X = 7√2≈9.89949
Thus ladder will reach to ≈ 9.9 (rouded-up) foot height in the building

8=56 7=42 6=30 5=20 3=?

m_a_m_a [10]

$3=6$

In this case, the pattern is the number, in this case, 3, multiplied by the number below it.

See?
$8\times7=56\\7\times6=42\\6\times5=30\\5\times4=20\\3\times2=6$

Hope this helped :)
